Control of an Electromechanical Control Actuation System Using a Fractional Order Proportional, Integral, and Derivative-Type Controller

In this study, the usefulness of a fractional order PID (proportional plus integral plus derivative)-type controller is investigated on the control of an electromechanical control actuation system. In this extent, the mathematical model of an electromechanically-actuated control actuation system considered is obtained in the continuous time domain first and then a control system with an integer PID-type controller is constructed by regarding this model. Having performed the computer simulations using the fractional order controllers which are designated by defining the integral and derivative actions in a fractional manner, the transient response characteristics of the proposed fractional order control systems are compared to those of the integer order control systems. Eventually, it is observed that satisfactory results are attained such that they can safely be implemented on a physical control actuation system mechanism developed.
